What webhook_listen_stop does on AirMCP
AI agents invoke webhook_listen_stop to trigger actions in AirMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why webhook_listen_stop is rated High
This tool triggers an external operation (stopping a listener and releasing network resources) whose effects depend on which listener instance is running. While not destructive (the action is reversible—the listener can be restarted), it is an active execution that modifies system state (port closure, process termination).
From the tool's definition Tool name 'webhook_listen_stop' indicates it stops a running webhook listener and closes its port. Description states it 'close[s] its port,' which is a network-level operational action.
Attacks that exploit this kind of access
The rule that runs webhook_listen_stop safely
PolicyLayer is an MCP gateway: it sits between your AI agents and AirMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For webhook_listen_stop, this is the rule to start with:
webhook_listen_stop stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect AirMCP, apply this rule, and every webhook_listen_stop call is checked against it from then on.
Questions about webhook_listen_stop
Stop the running webhook listener and close its port. Idempotent — safe to call when none is running. It is categorised as a Execute tool in the AirMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Air MCP server in PolicyLayer and add a rule for webhook_listen_stop: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AirMCP. Nothing to install.
webhook_listen_stop is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the webhook_listen_stop rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for webhook_listen_stop. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
webhook_listen_stop is provided by the Air MCP server (airmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
